Specification of Letters Patent No. 30,568, dated November 6, 1860.

To all whom it may concern:

Be it known that I, Mosics \V. DILLING- HAM, of Charlestown, in the county of Middlesex and State of Massachusetts, have invented an Improved Hydrocarbon-Vapor Generator and Burner; and I do hereby declare the same to be fully described in the following specification and represented in the accompanying drawings, of which Figure 1, denotes a top view; Fig. 2, a side elevation; Fig. 3, a vertical and longitudinal section and Fig. 4, a horizontal section of it, this latter section being taken through the vaporizing cup applied to the wick tube. Fig. 5 is a horizontal section of the lozenge shaped vapor heater arranged between the burner and the wick tube.

In these drawings, A, exhibits the wick tube of an ordinary lamp for vaporizing and inflaming a hydrocarbon fluid for the purpose of illumination. The said tube is to extend from or into the lamp reservoir and contain a wick, a, in order that the liquid hydrocarbon, whatever it may be, may be elevated into the tube by capillary attraction. The said wick tube is surmounted by a thimble or cap B, which is screwed upon its upper end and constructed with passages c, (5, leading through itas shown in Fig. 5, and particularly in Fig. (3, which is a vertical section of such cap B. This cap is also constructed in such manner as to screw through a lozenge shaped copper block or heater C, and into a hemispherical cup or burner 1), having a discharging jet slit 6, each end of which should terminate in a jet hole or orifice f, so formed and inclined as to cause a stream of vapor while being discharged from it to impinge directly on and along the top surface of the heater C. The said heater (whose object is to heat and attenuate the vapor) is constructed with axial passages g, It, which radiate from its central screw opening, 2', as shown in Fig. 5. The said passages, g, h at their outer ends lead respectively into the vertices of two V shaped passages, m, m, a, 7%, such passages being arranged in the heater and made to open into each other at is, Z, as shown in Fig. 5. Furthermore, the passages g, h, at

their inner ends open respectively in the passages, c, d, of the thimble or cap B. By means of the said passages, 0, cl, the combustible vapor generated in the Wick tube is led from such tube through the heater and into the burner. In its course, the vapor rises through the passage d, and passes into and through the passage 72,, from whence it flows into and through both branches of the passage m, thence into and through the passage, g, and finally into and through the passage, 0. As the burner is secured on the top of the cap, B, the effluent vapor, when inflamed will raise the temperature of the heater to such extent as not only to enable it to heat and expand the vapor passing through it (and thereby improve its inflammable and lighting properties) but to convey heat to the wick tube in order to vaporize the liquid taken up by th wick. The wick tube is surrounded by a cup, E, which is fitted loosely upon the wick tube and is formed in part by an annulus or col lar, 0, which answers the purpose of a valve for the closing of a discharging hole or passage, 79, made through the side of the wick tube as shown in Fig. 3. The collar, 0, also has a hole, 9, formed through it. turning the said cup on the wick tube, the two holes, 29, 7, may be brought into coincidence so as to form one passage leading from the interior of the wick tube and into the cup. By thus combining with the cup and the tube, a discharge passage and a closing valve we have the means of supplying the cup with liquid from the wick. For, when we may open the discharging passage p, liquid from the wick will escape into the cup. By turning the cup, a little on the tube, we can cit-her close the passage, 9, or open it as circumstances may require.

Preparatory to vaporizing the liquid of the Wick, we so turn the cup E, on its collar as to open the passage, 19, and allow a portion of the liquid of the wick to escape into the cup and after a sufficient quantity of it has so escaped, it may be inflamed so as to heat up the wick tube and its lozenge heater 0. This will generate vapor, which, while flowing out of the burner, may be inflamed thereon, the heat of the escaping vapor, so inflamed, serving afterward to maintain the vaporization of the liquid taken up by the Wick. After the lamp has been put in op eration, the cup may be turned in the opposite direction so as to close the passage, 79.
